The frame body 80 is disposed across the wall of the sound hole 111 to be opposite to the portion of the dust-proof member 70 facing the sound hole 111, so as to prevent the dust-proof member 70 from sinking into the sound hole 111 and prevent the dust-proof member 70 from bending or even breaking. Further, the dust-proof member 70 is attached to the bottom of the mounting groove 112, and the frame body 80 is located at one side of the hole wall close to the dust-proof member 70 and attached to the dust-proof member 70. Thus, the bottoms of the frame body 80 and the mounting groove 112 can abut against the dust-proof piece 70, so as to prevent the dust-proof piece 70 from sinking. Further, the circumferential direction of the dust-proof member 70 extends from the sound outlet hole 111 to the groove wall of the mounting groove 112 and abuts against the groove wall of the mounting groove 112, so that the dust-proof member 70 can be prevented from moving relative to the top plate 11, and the stability of connection between the dust-proof member 70 and the top plate 11 can be improved. In this embodiment, the dust-proof member 70 has a mesh. The shape of the mesh is fan-ring shape. It is understood that in other embodiments, the shape of the mesh may be circular, triangular, square, or elliptical. In order to improve the stability of the connection between the dust-proof member 70 and the top plate 11, the dust-proof member 70 and the wall of the mounting groove 112 may be bonded by an adhesive.

In one embodiment, with continued reference to fig. 1, 6 and 7, the top plate 11 is further provided with an annular protrusion 113, and the annular protrusion 113 extends from the groove wall to a side away from the top plate 11.
